JALOUSIE WEATHER STRIPPING 2 Sheets-Sheet 2 Filed Sept. 28. 1953 INVENTOR ATTORNEYS 2,740,175 JALQUSIE WEATHER STREPPIN G Ernest Johnson Eaddy, Sn, Spartanburg, S. C. Application September 28, 1953, Serial No. 382,591 8 Claims. (Ci. 20-62) This invention relates to a weather sealing means for the ends of jalousie slats or louvers.

An object of this invention is to provide a weather sealing means for the ends of jalousie slats or louvers which is normally biased to an open or non-sealing position, and is moved to closed or sealing position when the slats or louvers are closed.

Another object of this invention is to provide an improved operator for a sealing means which is actuated by movement of the connector bar secured to the louvers.

In a modified form of this invention the sealing means is operated by means of a cam having a lever or handle fixed thereto.

With the above and other objects in view, my 'inven tion consists in the arrangement, combination and details of construction disclosed irr the drawings and specifications, and then more particularly pointed out in the appended claims.

In the drawings:

Figure l is a fragmentary front elevation of a jalousie having a weather stripping mounted thereon constructed according to an embodiment of this invention.

Figure 2 is an end elevation of the jalousie.

Figure 3 is a vertical section of the jalousie.

Figure 4 is a sectional view taken from line '4-4 of Figure 3.

Figure 5 is a sectional view taken from line 55 of Figure 1 showing the weather stripping in the closed position.

Figure 6 is a fragmentary horizontal section of a modified form of this invention, and

Figure 7 is a fragmentary vertical section of a modified form of this invention.

Referring to the drawings the numeral 10 designates generally a frame structure which is formed of a pair of verticalstiies 11, a top rail 12 and a sill 13. The stiles 11 are formed of an outer plate 14 having an inner right angle flange 15 with an intermediate outwardly projecting flange 16 positioned between the vertical edges of the plate 14. An outer right angle 17 extends from the outer edge plate 14 and is substantially shorter in length than the inner flange 15. An outwardly projecting flange 18 extends from the flange 17 and is disposed parallel with the plate 14. A plurality of louvers 19 are rockably disposed Within the frame .10 and each louver 19 includes a holder 20 having an obliquely disposed lever or arm 21 which is pivoted at 22't0 "the flange 18.

Each pair of holders 20 has secured thereon a transparent panel or louver member 23. The levers 21 extend upwardly and inwardly from the pivot 22, and a vertically disposed connecting bar 24 is pivotally connected as at 25 to the inner ends of the levers 21. A louver operator 26 of conventional construction is secured to the inner side of the flange 15 and includes a lever or arm 27 connected by means of a link 28 to the connecting bar 24. The top rail 12 is constructed similar to the stiles '14 and is'connected to the'stiles 14' bym'eans States atcnt of an angle shaped connecting member 29. The sill 13 includes a downwardly and outwardly inclined plate 30 having an inner vertical flange 31 with a flange 32 at the outer edge of the plate 30. An intermediate bracing flange 33 extends downwardly from the lower side of the'plate 30. The flange 32 has projecting horizontally and outwardly therefrom a narrow strip 34 and an outer vertical flange 35 extends from and is integral with outer strip 34. A vertically disposed rib 36 is carried by the upper side of the strip 34 and is adapted to receive a U-shaped weather stripping for sealing the lower one of the louvers 19.

In order to provide a means whereby the opposite ends of the louvers 19 will be weather sealed I have provided an elongated strip or bar 37 which is yieldably supported by means of a pair of obliquely angled springs 33 secured byfastening means 39 to the flange 17. The springs 38 constantly urge the strip 37 outwardly to the released position shown in Figure 5. The strip 37 has extending angularly and inwardly therefrom a plurality of flanges 40 which in the inner position of the strip 37 are adapted to project over the outer ends of the louvers 19 as shown in Figure 4. Each flange 40 has mounted thereon a U-shaped weather stripping 41 which may be formed of rubber, Vinylite or the like. The weather stripping carrier which includes the strip or bar 37 and the flanges 4tlhas secured to the outer side thereof a plate 42 having an angularly disposed lug 43 projecting from the inner edge thereof.

A spring pressed plunger 44 is slidable through the flange 17 and through asupport 4S projecting inwardly from the plate 14. The plunger '44 is constantly urged inwardly by means of a spring 46 interposed in the inner side of flange 17 and collar 47 which is fixed on the plunger 44. The connecting bar 23 is formed with an outwardly projecting flange 48 and a plunger operating cam 49 is carried by the flange 43 in the position to bear against the inner end of plunger 44 when the bar 24 is moved upwardly to louver closing position as shown in Figure 3.

The cam 49 is inclined relative to the vertical in a manner whereby upon downward movement of bar 24 to louver opening position, plunger 44 will be quickly released so that springs 38 will swing the weather stripping carrier 37 outwardly to released position before thelouvers 19 are rocked on the pivots 22.

Referring now to Figure 7 there is disclosed a modified form of the invention wherein the plunger 44a is of a length to project through flange 17a and inner flange 15a, and -to bear against a circular plunger operating cam 50 mounted on a pivot 51 carried by a bracket 52 which is secured to the inner flange 15a. The cam 50 has projecting therefrom a handle or operator 53 so that cam 50 may be manually rocked to move plunger 44a outwardly to weather sealing position, or plunger 44:: may be moved inwardly by means of spring 46a to released position.

-In the use and operation of this device the louvers 19 may be opened by adjusting operator '26 at which time connecting bar 24 will be moved downwardly. At the time bar 24 moves downwardly cam 49 will release plunger 44 so that carrier 37 may be swungoutwardly to released position by the springs 38. When the louvers 19 are closed .by upward movement of connecting bar A 24, cam 49 on the last portion of the upward and outward movement of bar 24 will strike plunger 44 and move this plunger outwardly to thereby swing carrier 37 inwardly to weather sealing position with weather stripping members 44 and flanges 40 overlying the outer sides of louvers 19 at the ends of the louvers.

The weather stripping or sealing means hereinbefore described will provide an automatic means .for automatically sealing the outer ends of the louvers of the jalousie when the louvers are closed so that no dust, moisture or air will be permitted to pass about the opposite ends of the louvers.
